Key Benefits

Medical-Grade 316 Stainless Steel:** The interior is crafted from premium SUS316 stainless steel, surpassing standard 304 steel in durability and corrosion resistance. This medical-grade material is "fearless of acids and alkalis," making it perfectly safe for coffee, tea, juices, and carbonated drinks without any metallic aftertaste.

One-Piece Seamless Liner:** Utilizing advanced spinning technology, the inner liner is formed as a single, seamless piece. By eliminating internal weld seams, the bottle prevents the buildup of bacteria, tea stains, and residue, ensuring a more hygienic drinking experience and effortless cleaning.

12-Hour Thermal Performance:** Engineered with a sophisticated seven-layer barrier system, this tumbler provides a 12-hour lock on both heat and cold. Whether you need a steaming hot tea in the morning or ice-cold water in the afternoon, the OTE tumbler preserves the original temperature and flavor profile.

Magnetic Polishing Technology:** The drinking rim undergoes over 10,000 cycles of magnetic polishing to remove oxidation layers and surface imperfections. This results in an ultra-smooth, burr-free finish that feels comfortable against the lips and boasts a brilliant, high-gloss shine.

360° Leak-Proof Security:** Featuring a precision-cast stainless steel lid and a threaded food-grade stopper, the bottle offers a complete airtight seal. You can toss it into your handbag or backpack with total confidence, knowing it is fully leak-proof and travel-ready.
